Drill Bit SDS‑Max Smart 400 mm — Smart 12-012

SDS-Max drill bit Smart 400 mm — Smart 12-012 is a long working-bit designed for use with SDS-Max rotary hammers and demolition hammers. It is intended for drilling and chiselling in concrete, masonry and similarly hard mineral materials. The 400 mm working length provides extended reach for through-holes and deep anchor or dowel installations while the SDS-Max shank ensures firm, vibration-resistant connection to compatible power tools.

Advantages

The drill bit combines a durable carbide tip geometry with a reinforced steel body to resist wear during heavy-duty use. Its SDS-Max connection delivers stable engagement with rotary hammers, reducing slippage and improving energy transfer for efficient drilling. The long 400 mm length allows access to deeper drilling points without the need for extensions, and the design suits both rotary drilling and chiselling tasks, offering versatility on construction and renovation sites.

Suitable for

• Drilling through reinforced concrete and solid masonry for anchors and dowels
• Creating deep through-holes and service passages
• Chiselling and light demolition work with rotary hammers
• Renovation and construction projects requiring extended-reach drilling

Key specifications

• Working length: 400 mm
• Shank type: SDS-Max
• Application materials: concrete, masonry and other hard mineral materials
• Suitable tool types: SDS-Max rotary hammers and demolition hammers
• Intended use: drilling and chiselling for heavy-duty construction tasks

How to use

Select an SDS-Max compatible rotary hammer or demolition hammer with the appropriate power rating for the material and hole diameter. Securely insert the SDS-Max shank into the tool’s chuck until it locks. Mark the drilling point, start at low speed to locate the position, then apply steady axial pressure while operating in hammer-drill mode for drilling concrete or masonry. For chiselling, switch to the chisel/stop mode if available and use controlled, guided strokes. Withdraw the bit periodically to clear debris and reduce heat build-up.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask. Use the bit with tools that match the recommended SDS-Max shank interface and follow the tool manufacturer’s guidelines for speed, impact energy and maintenance to ensure safe and effective performance.
